Crabgrass Control: Timing Matters More Than Herbicide

Q: Drive XLR8 label requires crop oil adjuvant. What is that?

A: Adjuvants improve pesticide performance. Methylated seed oil helps Drive adhere longer. But at this time of year, killing crabgrass is pointless—it's already dropped thousands of seeds. Best control: apply pre-emergent next March to stop germination.
